Childhood immunisation is one of the priority health targets for New Zealand. Despite having made excellent progress in gaining high immunisation rates in the past ten years, we have not fully attained the stated goals of 95% fully immunised at 2 years and 8 months of age.

Aims: To determine whether knowledge gained from general practices with high childhood immunisation coverage rates and timeliness of delivery can be translated into strategies and actions in practices with low immunisation coverage and lead to a successful increase in their childhood immunisation rates, timeliness of delivery and reduction in immunisation inequalities.

Methods: A randomised controlled intervention study was undertaken of General Practice Medical Centres from three specific DHB regions in New Zealand with low rates of childhood immunisation coverage.
